Abstract:
A 9 year old male presented with history of loss of speech and seizure disorder for two years duration. The boy was developmentally normal before the onset of seizures. Examination of higher mental function revealed excessive hyperactivity, self destructive behaviour and decreased attention span. Audiological evaluation showed bilaterally normal hearing thresholds and he started communicating with signs. EEG showed repetitive spike and epileptiform activity from bilateral parieto-occipital regions. Clinical features and EEG led to a diagnosis of Landau Kleffner Syndrome (LKS). Child was started on steroid, anti-epileptic drug, speech and behavioural therapy immediately and improvement in the symptoms and reduced seizure activity was observed.
